Ruckus Wireless Inc. has begun pitching telcos a wireless-router multimedia home networking solution based on its �BeamFlex� directional-antenna technology. Current in-home Wi-Fi solutions suffer from inadequate range, spotty coverage, interference and performance fluctuations, even for data, Ruckus vice president of products Dave Logan said. Delivering video using IPTV only complicates matters. But Ruckus� BeamFlex technology constantly looks for the best signal path between devices in the home and steers RF signals around interference, Logan said, identifying and prioritizing traffic for transmission. At 25 to 35 feet, Ruckus can transmit 25 megabits per second to 30 mbps through one to two walls, Logan said. At 50 to 75 feet, and three to four walls, Ruckus can achieve 18 to 20 mbps, he added. Ruckus installs a main router next to the digital-subscriber-line modem, then adapters at each consumer device, such as the IPTV set-top. Hong Kong operator PCCW Ltd. is the first customer for the service, Logan said, with most of the current interest coming from Asian and European operators.
The rapid evolution of artificial intelligence (AI) and hyperscale cloud computing is fundamentally reshaping data center infrastructure, and liquid cooling is emerging as an indispensable solution. As traditional air-cooled systems reach their physical limits, the IT industry is under pressure to adopt more efficient thermal management strategies to meet growing demands, while complying with stringent environmental regulations. Liquid Cooling Market Development The latest ABI Research analysis reveals momentum in liquid cooling adoption. Installations are forecast to quadruple between 2023 and 2030. The market will reach $3.7 billion in value by the decade's end, with a CAGR of 22 percent. The urgency behind these numbers becomes clear when examining energy metrics: liquid cooling systems demonstrate 40 percent greater energy efficiency when compared to conventional air-cooling architectures, while simultaneously enabling ~300-500 percent increases in computational density per rac...
